There are some advantages and disadvantages to utilizing both internal combustion (IC) and electric trucks.
Electric engines cost less to maintain during their lifetime because they require much less maintenance. The battery must last five years minimum if the manufacturer's charging and maintenance guidelines are followed. Overnight charging costs are generally low. Electric trucks tend to be highly maneuverable and compact units, specially the kinds with three wheels. Drive, tilt, lift, auxiliary and acceleration speeds are adaptable and can be changed depending on the application and the preferences of the driver. Electric trucks are not noisy, and are easier on the environment.
Electric trucks are not suitable for use in wet conditions. Due to the need for battery recharging, they cannot be utilized continuously. They are not suitable on rough terrain. The energy consumption is high on ramp work and continuous high lifts.
Best to be continuously utilized outdoors and on surfaces that are not even is the advantage of an IC engine diesel/LPG. With no requirement for battery charging, the forklift could be utilized throughout the evening and overnight. Supply and transport of fuel must be factored into expenses. Initial expenses are less than for an electric truck, but long term expenses related to fuel and maintenance are higher. IC engines have larger capacities than electric, but less adaptability. LPG could be utilized in some indoor applications. IC Engine diesel/LPG makes higher emissions and more noise than electric. LPG has lower emissions compared to diesel.
